1.4.1 Outdoor unit .

Flexible and easy installation

The outdoor can meet the higher request of installation. From the specifications, you will find for

each unit, how long and how high the piping will be, which will be convenient for design and installation.

Optional safety devices and much more precision control device

a. Ambient temperature sensor, coil temperature sensor and compressor temperature sensor

make the temperature control and defrosting control more precise.

b. High/low pressure switch can feel the discharging pipe pressure and suction pipe pressure on

time and precisely. If the pressure is too low or too high, it will stop the compressor to prevent it

being damaged for the sake of pressure.

c. 3 minutes delay protection for the compressor, the device can protect the compressor from

some damages and make the compressor have a long life.

Silent operation

New design of long piping length and large drop

1.4.2 Decent convertible indoor unit

Optional installation mode

The indoor unit can be installed on the floor or to the ceiling, it is determined by the host favor and

the room décor. It is more convenient to service and installation.

Silent operation

The convertible unit is equipped with a high efficient, smooth, multi-blade centrifugal fan, which

generates a powerful but gentle airflow to any corner in the room.

Space-saving design

An innovative fan and the ultra thin heat exchanger result in the ultra thin convertible unit. Fully

adjustable mounting brackets make it possible to install the unit enven in the tightest places. Less than

199mm (for HDU-18) of vertical direction are required for installation.

Large angle air supplying

I00º wide angle louvers and 70º wide angle blades design to make a precise control of the airflow,

it equably distributes the comfortable air to every coner of the room

Automatically control of airflow direction for fast temperature adjusting

Central control function, if connected with a central controller

Commercial Air Conditioner Model: HCFU-18/28CF03

HCFU-18/28HF03

Carefully read the following information in order to operate the airconditioner correctly.

Below are listed three kinds of Safety Cautions and Suggestions.

WARNING!

CAUTI N! Incorrect operations may result in injuries or machine damages; in some cases may

cause serious consequences.

Incorrect operations may result in severe consequences of death or serious injuries.

INSTRUCTI NS: hese information can ensure the correct operation of the machine.

Be sure to conform with the following important Safety Cautions.

The Safety Cautions should be at hand so that they can be checked at any time when needed.

If the conditioner is transferred to the new user, this manual should be as well transferred to the new user.

WARNING!

If any abnormal phenomena is found

(e. g.smell of firing), please cut off the

power supply immediately, and contact

the dealer to find out the handling

method.

Don't dismantle the outlet of the

outdoor unit.

he exposure of fan is very dangerous

whichmay harm human beings.

switch

off

In such case, to continue using the

conditioner will damage the conditioner,

and may cause electrical shock or fire

hazard.

Incorrect maintenance and repairment

may cause water leak, electrical shock

and fire hazard.

When need maintenance and repairment,

call dealer to handle it.

After a long time use of air-conditioner

the base should be checked for any

damages.

If the damaged base is not repaired, the

unit may fall down and cause accidents.
